Diplôme : Master RechercheThe climate change experienced over the last years, either from anthropogenic or natural causes, is modifying the biosphere in a perceptible way. Phenology, physiology, species distribution and interactions between plants are highly dependent on the climate. This study focuses on the monitoring of phenology and on its spatial and temporal dynamics in the Pyrenean forested areas. Mountains are model ecosystems as they present a thermal gradient though their altitudinal gradient. Vegetation seasonal dynamics was estimated with PVI vegetation index observed from low resolution SPOT/VEGETATION sensor (VGT) and landuse map Corinne Land Cover 2000. Spatial disaggregation of the signal was conducted with a non-parametrica...
